To LH 'Lu/wht it mrtg concern:

Be it known that.. We, BERNARD T. Mo- GLONE. and GEORGE Rosspcitizensofxthe AUnited States, residing at Chicago, Illinois, and Hammond,Indiana,.respectivel v, have invented certain new and useful- Improve-.ducing bus ments in asting-Machines,'of which K Our'vention.relatesto.casting-machines, and more Earticularlyivto machinesfonproings ands'imilar articles; andits objects 'are toprovide, anapparatus of a simpleand'durablle construction which can be operated at.a Icoinparatively high speed, to provide ,an apparatus iii-which thefinished article can be readilyreinoved from the mold,

ltofprovid'e anapparatus -wliicli will permit of the use cfa sectionallmatrix, whereby easy removahility of .the casting is attained,

and to previd'ea machine in Vwhich the ejector.

constitutes one sideofv the mold. These'objects and other l advantages,which will hereinafter appea-1",We attainbymeans of the constructionillu stratedf-in preferred form in the accompanvingdrawings, wherein-Figure 1- is a yiew partly inl section and vpartly in elevation', oiour' improved apparatusfwith 'the 4parts in position for casting.

Fig. gis a vew'smilar tolfig. l of the upper part ofl the devicewithgtlie fn'iold-bottom in its raised position, the flatrx removed, and

a completed casting nestingg upon the `bottom just 'as itl comesfromtliernatrix; and Fig. 3

is a cross-section taken ontlie line 3 of Fig'. 1.

In the accompanying drawings the object illustrated as cast is abushing, and thisis what 'the'l device is primarily i ended: to produce;but it is ap arent vth O a plied to t ie producti ,y "man other artic esand is not limited- .t'o bus ngs. The device consists of aflaskforcasing LLeupported upon a base 5 of any suitable yconstructionand to which it isi secured. Aimatrix 6 is slidably mounted within thecasing and rests upon a reciprocable bttorn? ,operated by meansof1a'rack'8, uponwhich it rests, mounted upon the base presently'described.

:The tbody portionl f ,theiraek hollow andis supportd'upon averticalgguide 10, secured to the base axially in lin'eiwith and belowthe casing 4. The 'rack 8 'slides freely the invention may bey y. uponthe guide 10- and is operated by means pieces of the` base 5. y

When it is desired to form a hollow article, a core-'piece 12 is secrred to the upper end of the vguide 10 and extends through the bottom 7and matrix 6 into the capf13, which rests upon the top of the flask orcasing 4. IThe core 12 also serves to; act as a guide for the movablebottoni 7, which slides freely thereon and serves to keep the same inalinement when it is beingraised by means of the rack 8 and pinion 9. i

In order to permit of the ready lremoval of the article cast from thematrix when the latter has been elevated above the casing in theposition shown in Fig. 2, the matrix may be made in two parts,- asshowninl Figs. 1 and .3, andmolt'enmetal is introduced into the matrixthrough the ouringgate14, formed in the periphery of t e same adjacentto the casing 4, and through the cap 13. The pouring-gate 14 ispreferably located at the point on the periphery of the matrix where thetwo sections come together, as illustrated in Fig. 3.

From the foregoing it will be 'seenthatin an apparatus:constructed inaccordance with our invention a great number of castings can be made ina vcomparatively short time, as the article can be removed from vthemold as soon'as'it has set andthe mold again made ready/by the raisingand lowering of the bottoniportion 7 without in any way disturbing themain flas'kor removing itl'from osition.

Furthermore, such an apparatus .Wi l permitl further be a parent that bythe-use of a' matrix slidab ein the casing-there will not be thelresistance to sliding motion in removing the casting that there wouldbe were the cast'- ing alone tov be pushed out, as' the heated metalwould take 'a much firmer hold upon the side ofthe casing than thematrix does.

Other advantages of thedevice will readily occur to those familiar withthe art'.

Having thus described our invention and illustrated its use, whatweclaim as new, and

. desire to secure by Letters `Patent, is the folv lowing:
